General Information continued-

IMPORTANT

Before proceeding, please inspect the water heater and its components for possible damage. DO NOT install any damaged components. If damage is evident then please contact the supplier where the water heater was purchased or the manufacturer listed on the rating plate for replacement parts.

Make sure that you check the rating plate and combination gas controlONLYon the

water heater to be certain that the type of gas being supplied corresponds with

the marking on the rating plate and combination gas control.

A sacrificial anode is used to extend tank life. REFERENCEThe removal of this anode, for

any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water. If this should happen, an

alternative anode may be purchased from the supplier that installed this water

heater. This will minimize the odor while protecting the tank. Additionally, the

INSTALLATION

LOCATING THE WATER HEATER

WARNING

Water heaters are heat producing appliances. To avoid damage or injury, do not store materials against the water heater or vent-airintake system. Use proper care to avoid unnecessary contact (especially by children) with the water heater andvent-airintake components.UNDER NO CIRCUMSTANCES

MUST FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINTONLY THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER HEATER,VENT-AIRINTAKE SYSTEM OR IN ANY LOCATION FROM

DO NOT install the water heater in any location where gasoline or flammable vapors are likely to be present.

WHICH FUMES COULD REACH THE WATER HEATER OR VENT-AIRINTAKE SYSTEM.REFERENCE inches(46 cm) above the floor and shall be located, or protected, to

Water Heaters in residential garages shall be installed so that all burner(s) and burner ignition device(s) are located not less than 18

avoid physical damage. For otherFORinstallations refer to local codes. In the absence of local codes, the water heater shall be installed in

compliance with the National Fuel Gas Code, ANSI Z223.1- (Latest VERSION

Edition) and/or in Canada, CA /CGA B149 Installation Codes (Latest Editions).

The location of this water heater is of the utmost importance. Before installing this water heater, read the installation section of these instructions. After

reading these installation and operating instructions, select a location for the waterINTERNETheater where the floor is level and is easily accessible to gas and water supply lines.DO NOT locate the water heater where water lines could

be subjected to freezing temperatures. Make sure the cold water pipes are not located directly above the gas control so that condensate during humid weather does not drip on the controls.

Installation (Locating The Water Heater) continued-

Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals. These materials are corrosive at very low concentration levels with little or no

odor to reveal their presence. NOTE: DAMAGE TO THE WATER HEATER

CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY

THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF

ONLY

 

EXPOSURE HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY

CORROSIVE COMPOUNDS IN THE VICINITY OF THE WATER HEATER.

WARNING

 

Liquefied petroleum gases/propane gas are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.

IF YOU SMELL GAS:

Installation (Locating The Water Heater) continued-

WARNING

DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING:

Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in the detection of the gas.

Most people recognize this odor as a “sulfur” or “rotten ONLYegg” smell.

Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or ”fade”, and not be as readily

detectable. REFERENCE

If you have a diminished sense of smell, or are in any way unsure of the presence of gas, immediately contact your gas supplier from a neighbor’s telephone.

Gas detectors are available. Contact your gas supplier, or plumbing professional, for more information.

The water heater must be located closeFORenough to the outside wall to keep the venting distance within the maximum distance described in the installation

valveINTERNETwill not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be avoided, a

suitable drain pan, adequately drained, be installed under the water heater. The pan must not restrict combustion airflow. The drain pan must be no greater than 1-½inches(3.8 cm) deep and have a minimum length and width of at least four (4) inches(10.2 cm) measured from the jacket of the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least 3/4 inch(1.9 cm) in diameter and pitched for proper drainage.

It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve.
